Coordinate the preparation of organosilicon compounds in the polymer synthesis

. 6 × 10 (n ・ cm). Five-and six-coordinated silicon compounds coordinated sets silicide material has a significantly different, which is very stable, not afraid of water, even in aqueous solution can be generated, but it is the reaction of nucleophilic reagents are replaced by four silicon products, thus limiting its application. Five-coordinated silicon compounds and the reaction of nucleophiles to replace the single and double substituted silicon compounds, there is great development prospects. Laine significance of the study is that he created a low-temperature synthesis of coordination compounds of organic silica sets a precedent. This approach has three advantages: (1) energy consumption; (2) a rich source of raw materials, low cost, silicon dioxide, accounting for the crust 1 / 4, hexanediol is also very cheap; (3) pollution. 3, poly silicon material monomer units in our laboratory on the basis of Laine, starting from five coordinated silicon, and compounds containing organic functional groups the reaction of silicon monomer, Laine done in this area: 【for less, mainly for high performance of a】 O6 preparation of a ceramic glass can be. Our laboratory Liu Anhua 'l1 can use with the active compounds with the five southern coordinated silicon reaction. Reaction is: UL, -0 \ M + / 0 - ~ ... [\Ma salt is not soluble in alcohol precipitate, X-ray crystallography, NMR, IR 4 were proved its structure at low temperature France and Taiwan into the prospect of organic silicon monomer has a very important prospect, it is consistent with the requirements of modern industry, such as low energy consumption, no sludge pollution, raw materials,[link widoczny dla zalogowanych], cheap,[link widoczny dla zalogowanych], abundant source. In the introduction of pentacoordinate silicon double bond, epoxy bond, so that together units, generating silicon polymers, will have its unique nature, to be further research and development.
